Abstract: In the title compound, C₁₉H₁₄N₄, which was crystallized from dimethyl sulfoxide, the arene and heterocyclic rings of the lophine analogue framework differ only slightly from coplanarity (dihedral angles range from 8.8 to 20.2°), and intramolecular N-HN and C-HN interactions help to establish the conformation. The crystal packing features a number of weak C-HN, N-HN hydrogen-bond type contacts, and C-H interactions, leading to the formation of a herringbone structure.
